GE VMIVME-4140 VMIVME-4140-001 32 channel 12 bit analog output

Functional Characteristics
Introduction: The VMIVME-4140 Analog Output Board
provides 32 high quality analog output channels with 12-bit
resolution, and can source or sink 10 mA at ±10 V. Each
output has a dedicated D/A Converter (DAC) assigned to it.
The analog outputs can be disconnected from the field wiring
for offline testing. Calibration and self-test are initiated by a
VMEbus system reset or by execution of a software
command. During calibration, a table of offset and gain
coefficients is compiled and stored in RAM. There is an entry
for offset and gain corresponding to each of the 32 channels
configured in each of the six output voltage ranges.
Self-Test: Self-Test is run automatically after system reset.
The Self-Test Register indicates success or failure and can
indicate the channel which has failed.
Front Panel Status LED: The LED is illuminated after a
system reset. The LED is extinguished on the successful
completion of self-test and autocalibration. The LED can also
be turned ON and OFF under software control.
